RPR Ryegrass

Regenerating Perennial Ryegrass

Regenerating Perennial Ryegrass, or RPR, tolerates heavy traffic while maintaining its overall quality and appearance. With strong recuperative ability, RPR outperforms traditional perennial ryegrass when the games start. It is RPR’s unique regenerating ability that separates it from both traditional and spreading perennial ryegrasses.

Resilient and tolerant of tough summer conditions, when perennial ryegrass is the turf of choice, RPR is the ideal selection for your sports field, golf course, recreational turf area, home and commercial lawn.

Shady Areas

RPR has a moderate shade tolerance. We usually recommend that it needs 4-5 hours of direct, unfiltered sunlight per day but more than that if it is filtered sunlight. Like all grasses, RPR needs sunlight to survive and will begin to thin out if it isn’t getting the light it needs.

Watering

An established RPR lawn needs approximately 1 inch of water per week during the active growing season, either from natural rainfall or irrigation. RPR in shady areas will not need as much water. However, for soils with heavy sand content, it’s possible that the grass will need more than 1 inch per week because the soil wont hold enough moisture.

Fertilization

Generically, we recommend a fertilizer in the spring with a 1-0-1 ratio (like a 15-0-15) and in the fall, a fertilizer with a 1-0-2 ratio (like an 8-0-16.) The numbers are Nitrogen – Phosphorus – Potassium. These are generic recommendations that are meant to work for a wide area. If you choose to fertilize in the summer months, use only products that are low in nitrogen and slow release. Products containing iron will enhance color.

Mowing

You should mow RPR optimally every 5-7 days, at a height between .5 – 2 inches. Heights above 2 inches will begin to reduce turf quality and encourage thatch buildup. Thatch can lead to turfgrass disease and creates the perfect environment for insects.
